New submission from Sebastian Berg:
In NumPy we decided some time ago that if you have a multi dimensional buffer,
shaped for example 1x10, then this buffer should be considered both C- and
F-contiguous. Currently, some buffers which can be used validly in a contiguous
fashion are rejected.

#12845 should be closed, seems like a bug in some old version. The definition

To be clear, the important part here, is that to me all elements *can* be
